Frame rate dectection problem : hang on video and audio

[gvoyau]

Hello,

I try to use avidemux 2.6.5 for the first time, on HD recordings (MP4, 1080p) from my Samsung ATIV S Windows Phone.

If I made a simple video and audio copy, the result is very bad : hang on video and sound.
Frame rate has been change from 29.97 fps to 33.975 fps (detected).

I can solve the problem for the video by using a video filter "Change FPS" with this parameters :
- Source FPS : 29.97(NTSC)
- Destination FPS : 29.97(NTSC)

But for the audio track, I didn't found any solution for this bug (trying to re-encode using AAC or MP3, but nothing change).

Thanks for your help, and for this software who looks very very well

Regards
Guillaume

you can get one here (6 mo) : http://dl.free.fr/iqQHQ5saE

to download the file, you have to (I don't know if this page is french only) :
- launch the video (advertising)
- enter the code displayed under the video after a few seconds
- click on "Valider et télécharger le fichier"

What do you think of this problem ?

The video is indeed funny
Frame 64 is close to 1/33 sec of frame 63 hence avidemux behaviour
